Overview of chapters
Conceptually, this book is divided into three parts: fundamental concepts, tutorial, and reference. The first three chapters are a basic discussion of the TCP/IP protocols and services. This discussion provides the fundamental concepts necessary to understand the rest of the book. The remaining chapters provide a "how-to" tutorial. Chapters 4-7 discuss how to plan a network installation and configure the basic software necessary to get a network running. Chapters 8-10 discuss how to set up various important network services. The final chapters, 11-13, cover how to perform the ongoing tasks that are essential for a reliable network: troubleshooting, security, and keeping up with changing network information. The book concludes with a series of appendices that are technical references for important commands and programs.
